JQuery :: Cycle.js - Multiple Slideshows - And Timing - On Losing Window Focus

I've used the fantastic Cycle plugin on a couple of projects now, and it's worked really well.

I have four elements that use cycle, and I've used the timeout and delay options to have one box after another flip repeatedly.

This works well, so the first slide flips after 1 second, the second after 2 and so on, and then each slide continues to flip in turn.

Unfortunately, when I move to another browser tab or another window, then move back, returning focus to the window with the flip elements, the timing seems to go wrong. Each slide continues flipping, but they're no longer flipping one at a time.

My code runs as follows:

I'd like to see each one continue flipping in turn when I go back to the first tab.
